Random Number Generator Algorithms for JavaScript

index.js

// Generate a random decimal number between 0 and 1
var random = Math.random();

// Generate a whole number between 0 and the max number;
var maxNumber = 10;
var random = Math.floor(Math.random() * maxNumber); // Will generate a whole number between 0 and 9

// Generate random whole numbers within a given range
var min = 25;
var max = 38;
var random = Math.floor(Math.random() * (max - min + 1)) + min // Will generate a whole number between 25 and 38
